Answer:
4
Step-by-step explanation:
divide 9 by 3 the answer is 3 then divide 12 by 3 then the answer is 4
Write 90 out of 120 as a fraction-90/120. Simplify that until you can't any more and you get 3/4 of the original price.
Answer:
Step-by-step explanation:
Given that the chocolate factory "Charlie’s own" produces limited-time boxes with exactly 9 chocolates.
X is the weight of chocolate
X is N (5, 0.3) (since variance = 0.09, std dev =sqrt of variance = 0.3)
Probability for the box to weight <42.75 =
P(X<42.75)
=
Or 0.62% of boxed weigh <42.75
Answer:
h=404.89
Step-by-step explanation:
We are looking for side h, which is opposite of the observer. We know that the side adjacent to the observer is 500 feet. We also know that the angle from the observer to the bird is 39°. Because we have these values, SOH CAH TOA tells us that we should use tangent, opposite over adjacent.
We can set up our equation as follows:
tan(39°)=h/500
We can then solve for h:
500*tan(39°)=h
h=404.89
Answer:Let x = pay per hour as a carpenter and y = pay per hour as a blacksmith
Last week she worked 12 hours as a carpenter
earning 12x dollars
and 20 hours as a blacksmith
earning 20y dollars
and earned a total of $860
and those two things add up to 860.
Do the same with the other sentence, giving you a second equation.
